Sensory Decussation Level

Identified are the following structures:

Spinal Trigeminal Nucleus and Tract (SpTN, SpTTr)

Medial and Spinal Vestibular Nuclei (MVN, SpVN)

Lateral Cuneate Nucleus (LCN)

Inferior Cerebellar Peduncle (ICP)

Medial Longitudinal Fasciculus (MLF)

Tectospinal Tract (TST)

Hypoglossal Nuclei (12)

Dorsal Motor Nucleus (DMN)

Solitary Tract and Nucleus (ST, SN)

Nucleus Ambiguus (NA)

Reticular Formation (RF)

Note:

The Nucleus Ambiguus can be seen as a small cluster of red-stained neurons located ventrolaterally in the reticular formation (RF). The NA provides SVE innervation to branchial arch derived muscles of the pharynx and larynx, In addition, like the Dorsal Motor Nucleus, it also provides some preganglionic parasympathetic (GVE) innervation to the heart.
